Multilevel structural model with gsem

Dear all,

I'm facing some problems with gsem. I have a two-level hierarchy data with households [hhID] nested within areas[PSU].

I'd like to specify a SEM in which the measurement model expresses the relationship between the latent variable (defined at the household level) L1 and a set of binary observed items q1-q8, and the structural model has a multilevel structure that allows for decomposing the variance of the latent variable in its between- and within-area components.

The specification of the (empty) multilevel structural model is

L1_jk = v_00 + u_0k + e_jk

where u_0k and e_jk represent, respectively, residuals at level two and one (j is the subscript for the households and k subscript for the areas).

How can I code such a model using gsem?

My try (contaminating with code from xtmixed) has been:


gsem (L1->q1-q8, logit) (L1<- ||v001: )

But of course it does not work.

I've found a lot of material about latent variables specified at level two but few about multilevel structural model.

Can you please help me?

Many thanks,
F
